Have any of you ladies here dealt with Pre Menstrual Dyphoric Disorder?

This is newish to me, and seriously is causing me major problems. I am ok until a week and a half to two weeks before and then it hits. It is too the point where I am getting quite suicidal during this phase, and am even scared of myself, or scared to be left alone, in case I act on an impulse. This is not your normal PMS. This last one was really really bad. However now that is has passed I am pretty much right as rain, and totally frustrated.

I am just wondering if anyone has dealt with this, I read the usual treatment is antidepressants, which I am already taking an SSRI, so I don't know. I have noticed tho that the last year or so it has been getting worse and worse.

Really Bipolar is enough, I don't need this also. I am going to go see my dr. And I know I should not dx myself, but I have read over and over that there is a higher chance of having this with a mood disorder, and I do know that what I am going through is a bit extreme for PMS. Anyways, just putting it out there.

I know that menses can effect bipolar cycles, but I really feel it is more than that.
